Hi, in my notebook, I have a chip (namely O2 Micro OZ99x) that probably can do SMBALERTs for events (panel buttons in this case). The SMBus specification[1] says that it's optional. The only mentioning of alert reponse address (ARA) in the i2c-ali1535. And according to specs from intel[2], the i815 has it, too. I guess, the interrupt handler should check if the interrupt was due to an SMBALERT and then handle the alert properly by issuing a read from the ARA (0x0C), thus finding the device address. Then it should call the driver that was registered for that address. Was there any work done on this? I would really like to try this out with the above device combination, however the i2c-i810 doesn't even listen on the irq ?!?
